A high pressure fluid spray gun comprising an adjustable shoulder support with a rotatable head and a length adjustment mechanism. The high pressure gun also includes a reversible piston and seat operable by a manual trigger for directing the flow of high pressure fluid to discharge either through the gun barrel or to a dump chamber which is mounted on a swivel for convenient adjustment of the alignment of the dump hose. The high pressure inlet hose is connected to a "Y" fitting in the barrel to reduce the back thrust on the operator when the gun is being operated.
